IMPRGVEMENT IN CAR-AXLE BOXES.

Specification forming part of Letters Patent No. 193,064, dated July 10,1877; application filed June 26, 1877.

To all whom it may concern:

t Be it known that I, GEORGE WILLIAMS, of Mystic Bridge, in the countyof New London, and in the State of Connecticut, have vinvented certainnew and useful Improvements in Car Axle Journal Box and Lubricator; anddo hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, making a part of thisspecication.

The nature of my invention consists in the construction and arrangementof a car-axle journal-box and lubricator therein, as will be hereinaftermore fully set forth.

In order to enable others skilled in the art to which myinventionappertains to make and` use the same, I will now proceed to describe itsconstruction and operation, referring to the 'annexed drawings, inwhich- Figure l is a longitudinal vertical section of a car-axlejournal-box embodying my invention. Fig. Zisa transverse verticalsection of the same. Figs. 3,4, 5, 6, and 7 are detached views of partsthereof.

A represents a car-axle journal-box of substantially the sameform asthose now generally in use. The outer end of the box A is closed bymeans ofa door, B, hinged to the box below its lower edge, and providedin the center at the top with a projection, b, through which passes ashort shaft, a, having its outer end made square, for the reception of awrench or key. On the inner end of the shaft a is secured aneccentric,C,the end of which is made in the form of a part of aright-hand screw, so that when turned to the right it will enter arecess, madein the top of the box, and wedge tightly therein to fastenthe door in its place.

It will thus be seen that the mechanism fork fastening the hinged dooris all on the outside; hence it will not become clogged with-oil anddirt to prevent the easy working of the same.

D represents the journal; E, the upper bearing; and Gthe wedge placedabove the journal in theusual manner. In the concavityof the hearing Eis made a longitudinal groove, as shown in Figs. 1 and 2, and anaperture, y, is made in the bearing connecting with said groove.

The upper surface of the bearing E onone side 'of the aperture y is madeinclined, and, with theaperture, is directly below an opening, z, in thewedge. On top of the `journalbox A is formed a box, A', with an aperturein the bottom leading into the opening z.

The box A is to be filled with such grease or other suitable materialthat will in ordinary temperature remain in asolid state. If the#journal then should heat and the box become too warm, the grease willmelt and pass down through the apertures z y, and by the groove vin thebearing be distributed all over the jour nal, cooling the same.

On the axle D, between the car-wheel H and the end of the box, areplaced two flanged collars, II, the adjoining ends of which are formedwith overlapping joints, as shown at e, and between the two flanges isplaced a spiral spring, d, which spreads the collars, so as to close theinner end of the box, preventing the escape of oil and excluding dirt.

In the bottom of the journal-box A is placed a box or drawer, J, havingcleats near each side under the bottom to form slides, so that said boxor drawer can easily slide to correspend with the lateral motion of thejournal. In this boxJ is placed a revolving cylinder composed of twocircular heads, K, placed upon a central shaft, f, and connected bymeans of longitudinal bars L, in each of which is securedV a brush, h,or its equivalent, for conveyingoil to the journal. The center-shaft fhas its bearings in boxes M, sliding vertically in guides N secured onthe inside of the ends of the oil-box J, and the journal-boxes M aresupported upon springs @l held. in said guides.

The outer structed is formed with a circumferential groove, into whichits a Harige, m., on the end of the journal D, so that when the car isin motion the cylinder will be revolved directly therefrom by friction,and thus supply oil to the journal. The springs i hold the cylinder soas to be always-tight enough on the dange m to revolve by friction.

By having the flange on the journal and the groove in the cylinder-head,the oil-feeding devices are brought in 4contact with the shaft head oflthe cylinder thus coin l 'pose, `and it 'is inot lia'bleto twistortu'rnfrom its proper position, and hence `cannot retard.v

the free movement ofthe shaft.

In place of having the brushes running longitudin ally, as abovedescribed, Ifm ay arrange them spirally around the cylinder, in whichcase the cylinder may be revolved by friction of the journal direct onthe brushes.

Having thus fully described my invention,ly what I claim as new, anddesire to secure by' July, A. D. 1875.

Letters Patent,is-

1. In combinationwith the box A, having frecess 'at itsltop, vthe doorB, hinged to the bottom of the box, extended above the top of ithefsame,and provided with a shortsha'ft, a, and eccentric C, to work in therecess as Set forth.

v2. The eombinatiom'withia icar-journjljb, wheel Hfand box A, of lche-t-woian ged 'collars, I I, constructed independent of the box `orwheel,formed with overlapping L-shaped joints e, and the exterior spring dsurroundling'the =same,"substantially asand for the'lpur- .poseshereinset forth.

v3. The combination, with a car-journahD, having flange m, of thecylinder K L, with lcircumferential@groove in the outer head, and withbrushes h, journalboxes M guides N, --and springs i, all substantiallyas and for the 'purposes herein set forth. l

In ltestimony that I claim'the `'foregoing I lhave hereunto set my handthis 13th day of B. LAT'HAM MILLER, O. L. EVERT.
